Btw, perhaps not the perfect question in this thread:But what should we use to keep servers running without a hardware rng available and without any external input besides the network?After having ssh and openvpn die because of no random and having the machines like dead and unreachable for me I use "ln -sf /dev/urandom /dev/random", but that does not feel so good.
